DD-625

The DD-625 is a surface launched, fluid assisted, mechanical horizontal directional drilling system with a tri-axle suspension mounted thrust frame. The DD-625 will provide field proven performance and excel when used for conducting large diameter and long reach pipeline crossings or utility construction projects.

Technology Spotlight: Wiggle Steer

The Wiggle Steer System provides the operator of a directional drill the means to rotate the drill pipe and subsequently the cutting head on the drill string back and forth over a predetermined range. This back and forth motion would cause the hole made by the cutting head to be more open in a particular direction and therefore facilitate steering of the drilling pipe in that direction under ground. The Wiggle Steer System will rotate the Drill Pipe in the Makeup (CW) direction while thrusting forward. It will then rotate the Drill Pipe in the Breakout (CCW) direction but will not thrust in the breakout direction. This method reduces the breakout torque and should prevent the drill string tool joints from parting down-hole.
